sirtokesalot Posted April 20, 2020 Share Posted April 20, 2020 today i did some work on an 04 outback for one of my fathers friends. it was here for some dash lights radio replacement and valve cover gaskets. i was also asked to look into the ticking sound when cold and low power issue. the ticking ive found the cause as a bad timing tensioner bouncing to the click sound. could an outback jump time a tooth and still run smoothly but just be down on power? or could it be something els. the car also has a p0420 code. no other codes stored in the ecu.

lmdew Posted April 20, 2020 Share Posted April 20, 2020 Yes, I've seen it. Also knock sensor could cause the loss of power. 1 Quote Link to comment Share on other sites More sharing options...

lmdew Posted April 21, 2020 Share Posted April 21, 2020 Usually dose have a code. But if the belt checks out, a cheap check. Quote Link to comment Share on other sites More sharing options...

Rampage Posted April 21, 2020 Share Posted April 21, 2020 My wife was driving our 95 RHD EJ22 Legacy and the engine shut off. She coasted off the road and it started right up and worked fine. Then a couple days later it did the same thing. After checking everything I could think of, I found a post here that said to check the knock sensor. The housing was cracked. NO codes, but it shut the engine off. Replaced it and no more problems. I would check the timing. I've read other posts here that with one tooth off it ran ok, but did not have the power it should. 1 Quote Link to comment Share on other sites More sharing options...

I don’t think a knock sensor can do that! Maybe there’s also an issue with the idle air control valve and in conjunction with a dodgy knock sensor the engine was able to stall out.

It happened three times. The only thing I changed was the knock sensor and the problem went away. Quote Link to comment Share on other sites More sharing options...
sirtokesalot Posted April 22, 2020 Author Share Posted April 22, 2020 (edited) update. took it apart it looked fine so i marked the belt pulled it apart changed the tensioner and put it back on my marks and after doing this it was 1 tooth off on the passenger side cam. rechecked i put the belt on the same way it came off ... yes. the passenger side cam was 1 tooth off. pulled it back apart fixed the timing put it all back together and seems to be running fine now. drove ti for 10 miles and let it idle in the driveway for a bit drove it again seems the 420 code is not coming back now ither. from what ive been told it woulda threw the light on in 10 to 15 miles before Edited April 22, 2020 by sirtokesalot 4 Quote Link to comment Share on other sites More sharing options...
